Synchron Poseidon Ice Diver
57 watches that match on case size, movement family, and price band. Sorted by how close the match is.
The closest alternative to the Synchron Poseidon Ice Diver is the Seiko Prospex Sea 1968 Heritage Diver's GMT Watch Limited Edition ($1,750) — looks nearly identical and Automatic. If price is the constraint, the Aigi Watches ARCTIC DIVER at $480 (vs $1,290 for the Poseidon Ice Diver) covers most of the same brief. From the independents, the Serket Watch Co Reef X is the standout microbrand take — looks nearly identical and Automatic. Stepping up, the Breitling Superocean Automatic ($5,700) is where the same idea goes with a bigger budget.
